Reference Match (RM): Isoform is FSM and within 50 bp of annotated transcription start and end sites.
Full Splice Match (FSM): Isoform with identical exon count and matching internal junctions; start and end may vary.
Incomplete Splice Match (ISM): Isoform missing some 5’ exons but with matching internal junctions.
Novel In Catalog (NIC): Isoform uses known splice sites but lacks FSM or ISM match.
Novel Not in Catalog (NNC): Isoform contains unannotated splice sites.
Genic Intron: Isoform entirely within an annotated intron.
